ators, but such means have beena source ofinuch trouble, inconvenience and expense.

Such brackets are usually held in place by screws engaging cast blocks set lnside the tank or reservoir chamber. I aim to elimmate both the blocks and the screws.

The main objects of this invention are to-provide an improved form of radiator hanger bracket and method of attaching same; to provide a combined radiator and bracket of unitary and substantially integral character; to provide for alighter construction of bracket without diminution of strength and resilience; to provide forrivet ing the bracket to the radiator tank without hindrance to subsequent assemblage and proper sealing of the'core-tank joints of the radiator adjacent to the bracket; to

provide for bending the bracket into final shape after riveting in place and after sealing of the joints; to so simplify. and unify the construction that .mounting and demounting may be more readily accomplished.

An illustrative embodiment of this invention is shown by the accompanying drawings in which Figure 1 is a front view of a radiator with the casing shell in place and with the chassis side bars shown in cross section.

Fig. 2 is a similar view with the chassis bars omitted and with the supporting brackets shown in their initial divergently extended joint sealing position, prior to bending upward into final shape.

Fig. 3 is a slightly enlarged fragmentary detail of the lower left hand corner with the shell removed and with the bracket disposed outwardly substantially as in Figure '2, the side portion of the shell and adjacent part of said bracket being indicated by dotted lines as they appear in their finished normal position. I I

Fig. 4 is a much enlarged plan of one of the bracket blanks prior to bending, and showing two rivet holes and a bolt hole.

In the construction shown in the drawings, the radiator 1 as a 'whole is supported on resilient brackets 2 bolted by the side blank.

bars 3 of the chassis, the, brackets being fastened directly on the bottom tank of-the core of-tne radiator, as shown in Fig. 3.

Said radiator comprises mainly. a ventilating core 4: in substantially integral combination with upper andlower bulk heads 5 and 6 respez' tively, the latter serving as a tanker reservoir for the water supply,

the said members 4, 5, and 6 being joined together and hermetically sealed asshown by the lower horizontal sealing line? on Figures 2 and 3 as usual in such devices.

The radiator casing shell .8 is in place i I and is shown; by full lines on Figures 1 and v 2, and preferably fastened to the core; The side part. 8 of the shellis; spaced somewhat fromthe in any well known manner.

side part 4- ofthe core as shown atj9 on; a

Figure 2: v i p In order to simplify the construction and the methodof assembling these radiators,

the bracket2 is first formed. from saablank is riveted directly and permanently to the bottom of the reservoir 6 before .the'latter is connected to the core 4i, ready access thus being had to the interior of said reservoir for setting the rivets 11, since thereservoir is' then open at the top A bolt hole 10 and rivet holes 10 are provided in said The purpose of adopting the initial form 1 of the bracket shown in Figures 2 and 3 is to permit ready access to the abutting edges of the reservoir 6 and the core 2 along the sealing line 7, especially at the sides, as indicated at 7. This permits the radiator latter are attached. Itis preferable to use an external soldered joint, which can be repaired from the outside, and it is accordingly necessary to solder all around the joints'between the brackets and the tank to stop any possible leakage through the rivet holes.

the brackets are positioned as shown in Figures 2 and 3, after which the free ends of the bracket are swung inwardly about the. t

Then the joint 7 is sealed after the bracket is riveted to the tank 6 and while i bending point 12 so as to fit snugly against a a medial reverse curve offset at '13 which the casing-part 8.,the latter being readily demountable and interchangeable.

In order that the radiator core" may be protected from injurious vibration such as might result from violent jolts the brackets 2 are formed of resilientmaterial and are sufliciently yielding to materially cushion the core. With this end in view, the blanks 10 are formed as shown in Figure 3 with provides for spacing the upper part of the bracket somewhat away from the core and casing as indicated at 14 on Figure 1. The

upper tip ;of the bracket'is bent at a right V In 'of the shell side part 8 an outward bulge the bending occurring naturally at point 12 1 whereit bears against the corner of the reservoir and the outward bulgev 17 serving to 1 provide the necessary clearance spacing as above explained and as shown in Figures 2 i and 3 -The bracket bends. and curves are preferably formed on a mandrel-as this insures precision and uniformity. The aper- "turedvlug-l8 on the lower edgeof the casing 1 accommodates the engine crank shaftextension' as will be understood.

It will beobservedthat the spacing let "providesfor horizontal cushioning and the medial oifsetatf 13 provides'for vertical or gravity' cushioning. Moreover, this construction simplifies the design in that it re duces the number of parts, screw seating blocks beingeliminated, and the core is made permanently unitary and substantially integral with the core support brackets.

Although but one specific embodiment of this invention has been herein shown and described it will be understood that numerous details of the construction shown may be altered or omitted without departing from the sp'iritof this invention as defined by the following claims. 7

. I claim: V

1. The method of assembling aradiator core, Water tank and support brackets for a motor vehicle, which consists in riveting the brackets to the exterior of the bottom of the Water tank, the brackets then being in a form to extend away from the sides of the tank, then attaching'the core to the top of thewater tank and externally soldering the joints between the brackets and the water tank, and finally bending the brackets inward convergently adjacent to the sides of the tank and co-assembled core into the form required for ultimate installation.

2. The method of fabricating automotive vehicle radiators, which consists in riveting supporting brackets to the bottom of the '3 water tank, with the outward ends ofthe brackets extending divergently from the sides of the tank, then attaching the radiator core to the top of the water tank and externally sealing the joints between the brackets and the tanks by soldering, then bending the extending, ends of the brackets up alongside the sides of the 'core,and' then attaching the shell to the core.
